System for quickly finding the whereabouts of friends

ABSTRACT

A method and/or system is disclosed allowing a user to quickly and easily obtain information on the location of another user or group of users. Such location information, may for example, be provided for quickly finding the whereabouts of friends, volunteers, employees, event attendees, etc. The system is comprised of a user application and a user connection server which utilizes push notification services. Accordingly, embodiments allow a user to ask, for example with a single button press/user selection, for the location of other users. In response to the request, the user can, for example with a single button press/user selection, choose to respond to the user. The requesting user then sees the location of the other user.

CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application claims the benefit of U.S. Provisional Patent Application 61/849,834 filed May 17, 2013 entitled “System for Quickly Finding the Whereabouts of Friends.”

FIELD OF THE INVENTION

This invention relates to the field of data communications and more particularly to a system for finding the location and/or status of other individuals.

BACKGROUND OF THE INVENTION

There are a wide range of instances where a group of individuals are coordinated for an event. Examples of such events can include, but are not limited to, birthday parties, weddings, christenings, funerals, school trips, concerts, business meetings, conferences, charity events, and reunions. Today, in order to set up such events a range of options exist with respect to communication tools including, for example, Simple Messaging Service (SMS), telephone, social media such as Facebook™, messaging services such as Twitter™, email, and web based services such as Google Events.

In the majority of instances these events are based at a particular location (e.g. an office, church, restaurant, concert hall, etc.) although in other instances these may be a range of locations (e.g. a charity run requiring volunteers at the start, finish and runner registration). When one or more of those invited or expected at a location does not appear then others must text, email, or call, trying to find out where they are. However, in many instances the missing individual(s) are currently travelling to that particular location and may, for example when driving, not be able to receive or reply to a telephone call, text, or email. At the same time they may not be familiar with the particular location, the neighbourhood or area around the particular location, etc. and hence actually find it difficult even when they are able to reply to provide an estimate of their arrival time or time to arrival.

Within the prior art there are smartphone applications that allow a user to track their friends. These include:

-   -   Trackster is an Apple iOS and Google Android smartphone Global         Positioning System (GPS) based application. It allows a user to         track, find and follow their friends who have also downloaded         the application. It provides this information on a map. It also         allows a user to tweet their location, choose who can track         them, and allow them to text their friends.     -   Loopt is a smartphone application supporting iOS, Blackberry 10         and OS operating systems, Android, and Windows mobile platforms.         Similar to Trackster the Loopt application allows a user to see         where their friends are who have also downloaded the application         and what they are doing.     -   BrightKite is a location-based social networking tool allowing a         user to post their location and track where people are. In         addition, BrightKite offers unlimited group texting with         multiple friends in various locations.     -   Yahoo Fire Eagle is a free application allowing a user to send         receive updates, track their friends, and see what is going on.     -   Find My Friends allows a user to locate their friends and family         from their Apple iOS devices such as iPhone, iPad, or iPod         touch. It displays upon a map where the user's friends are         relative to the user's location.     -   GPS Tracking Pro allows a user to track family and friends         through real-time location tracking using an Android device.     -   Google Latitude allows a user to view their friends upon a map,         control who sees their location, at what level of detail, and         check in at places to let friends know the user is there.

However, in all of these prior art applications it is a requirement that the user and the individual have not only a prior association within one another but that the individual has authorised the application to disclose their location. In the majority of these prior art applications it is also a requirement that the user and the individual are using the same application. In the majority of instances where the user and individual are not family or close friends then the individual does not wish to have the user know their location. In other instances, such as the Toronto Waterfront Marathon where there is a small organizing team and approximately 3,000 volunteers then ensuring all the volunteers have downloaded the application of choice of the event is an overhead the event can ill afford and then tracking a small number of volunteers within this larger number a significant issue as these prior art applications are primarily intended for tracking a small number of user's. Scrolling a list of 3,000 volunteers to enable, for example, the 10 missing volunteers to be located would take a user a significant period of time. Partitioning the list between multiple users only succeeds in creating additional management overhead and communications issues within the event organizers.

Accordingly, it would be beneficial to provide individuals, enterprises, organizers, etc. with the ability to establish allocation of an individual or group of individuals rapidly, with low complexity and management overhead, and without requiring that the two parties exploit the same software application or establish a relationship akin to friends within these prior art applications.

Other aspects and features of the present invention will become apparent to those ordinarily skilled in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures.

The system(s) and/or application(s) described below in respect of embodiments of the invention may be employed in a standalone manner or they may, alternatively, be a feature of or be used as part of a larger system for creating, managing, running and/or coordinating an event. Within the embodiments of the invention described below these are described with respect to “friend connections” (FCs). However, it would be understood by one of skill in the art that this may be generalised to the context of “user connections” wherein no formal relationship exists between the two users other than they are associated with at least a single event.

Referring to FIG. 1 there is depicted an example of an architecture for implementing a system according to embodiments of the invention. Accordingly, there is a FC server 100 which is connected to the cloud 107, i.e. the Internet, which is responsible for communications between all the Friend Connection Applications (FCAPs) 108, 109. FCAPs 108,109 can reside on PEDs and/or FEDs. To do this the FC server 100 communicates with various platforms, for example Apple™ push notification service 101 when communicating with Apple™ PEDs and/or FEDs, a Microsoft push notification service 102 when communicating with Microsoft PEDs and/or FEDs, Google cloud messaging 104 when communicating with Android PEDs and/or FEDs, and a Blackberry push notification service 103 when communicating with Blackberry PEDs and/or FEDs. All of these push notification services 101, 102, 103, 104 are standard and exist today. There are specific Representational State Transfer (REST) application programming interface (API) endpoints for the push notification service of each of these platforms. Users 105, 106 have an FCAP 109,108 downloaded onto their devices. The FCAPs 109, 108 interact with the device's display and location services. Within an embodiment of the invention there is a different variant of the FCAP 109, 108 for each of the different types of device: Apple, Android, Blackberry and Microsoft. Each device type provides a standard API to retrieve location data. Whilst the push notification services are described as communicating with PEDs and/or FEDs it is generally expected that embodiments of the invention will be exploited primarily with PEDs although they may be exploited with FEDs.

Now referring to FIG. 2 there is depicted an exemplary user interface for the FCAPs within a system according to an embodiment of the invention. User 1 105 has a list of friends that they are currently interested in. This may be, for example, a complete list of all the user's friends, or it may alternatively be a list derived from a pre-setup event or outing. In this example User 1 105 (Jane Doe) wishes to find the whereabouts of Terra Billings 200, e.g. User 2 106. They tap the “Where Are You?” button 201 next to Terra Billings 200. This triggers a push notification to be sent to User 2 106 (Terra Billings 200) device and a notification 202 to appear upon their device. The notification 202 includes the name of the person (Jane Doe) that wishes to know where User 2 106 (Terra Billings) is. All User 2 106 (Terra Billings) has to then do is to tap the “I'm Here” button 203 on the device. This causes the location of User 2 106 (Terra Billings) to be sent back to User 1 105 (Jane Doe), and when it is received it pops up a map 204 showing the location of user 2 106 (Terra Billings). Neither of users 1 or 2 105,106 has to type anything, or make a call. They just have to tap a button once. Further, user 1 and user 2 do not need to have any formal association. It is merely sufficient that user 1 has contact details relating to user 2 which may, for example, have been provided by user 2 to user 1 or to an enterprise associated with user 1. For example, a volunteer registering to an event may provide their email address allowing them to not only receive communications in respect of the event but also for them to receive such communications through their FCAP.

Referring to FIG. 3 there is depicted a message sequence chart according to an embodiment of the invention of the messages that go between the FCAP 1 109, the FC server 100, the push notification services 101, 102, 103,104 and the FCAP 2 108. FCAP 1 109 sends a “Where Are You′?” message 300 which includes the identity of User 1 105 and User 2 106 to the FC server 100. The FC server 100 then looks up the type of device that User 2 106 has and chooses the appropriate push notification service 101, 102, 103 or 104. It then sends the message 301 to the push notification service 101, 102, 103, 104 with the recipient being user 2's 106 device. The push notification service 101, 102, 103, 104 then sends the notification 302 onto the User 2 106 device. When the User 2 106 presses the “I'm Here” button, which is received by FCAP 2 108, FCAP 2 108 causes a message to be sent 303 to the FC server 100, which includes the identity of User 1 105 and User 2 106 and the location data of User 2 106 device. The FC server 100 then looks up the type of device that User 1 105 has and chooses the appropriate push notification service 101, 102, 103 or 104. It then sends the message 304 to the push notification service 101, 102, 103, 104 with the recipient being user 1's 105 device. The push notification service 101, 102, 103, 104 then sends the notification 305 on to the user 1 106 device. The FCAP 1 109 sees this notification and pops up a map showing the location of User 2 106.

Now referring to FIG. 4 there are depicted details of FCAP 1 109 and FCAP 2 108 according to an embodiment of the invention wherein both have FC server interfaces 400. This software is responsible for sending messages to the FC server 100 via the cloud 107. They also have push notification reception 404 software which is responsible for handling the receipt of push notifications from push notification services 101, 102, 103, and 104. The display interfaces 402 with each of FCAP 1 109 and FCAP 2 108 are responsible for displaying the correct images on the device. The list of friends 401 is data that the display interface 402 uses to display the list of friends to the user in selecting the user 109 to whom to send the request. Location data retrieval 403 software is responsible for retrieving location data from the device, such as for example by accessing GPS data with the device, accessing triangulation data of wireless transmitters associated with a wireless receiver of the device, an identity of a wireless node to which the device is connected and an identity or identities of one or more wireless beacons observable by a receiver or receivers of the device. Optionally, optical and/or other non-wireless sources of location information may be accessed. Optionally, location data may be derived from an ad-hoc network to which the device is connected rather than a fixed or installed network. Each device typically has an API that is freely accessible to do this.

Now referring to FIG. 5 there are depicted details of an FC server 100 according to an embodiment of the invention. FCAP interface 500 is software that receives messages from all the FCAPs 109, 108 via the cloud 107. It exploits reference to a list of subscribers 505 wherein this data is used to verify the sender's identity and to look up the type of device that they have. It receives two types of messages, “Where Are You?” and “I'm Here” coming from FCAPs 108, 109. It looks up the device type of the user 105,106 the message is being pushed to, which then lets it select the correct push notification interface 501, 502, 503, 504 to use to send the “Where Are You?” message to the recipient and the device type of the sender to send the “I'm Here” message in response. The push notification interfaces 501, 502, 503, 504 interface with the corresponding push notification services 101, 102, 103, 104.

Now referring to FIG. 6 there is depicted a network environment 600 within which embodiments of the invention may be employed supporting friend connection systems and friend connection applications/platforms (FCS-FCAPs) according to embodiments of the invention. Such FCA-FCAPs, for example supporting multiple device types, multiple communication channels, fixed content, dynamic content, etc. As shown first and second user groups 600A and 600B respectively interface to a telecommunications network 600. Within the representative telecommunication architecture a remote central exchange 680 communicates with the remainder of a telecommunication service providers network via the network 600 which may include for example long-haul OC-48/OC-192 backbone elements, an OC-48 wide area network (WAN), a Passive Optical Network, and a Wireless Link. The central exchange 680 is connected via the network 600 to local, regional, and international exchanges (not shown for clarity) and therein through network 600 to first and second cellular APs 695A and 695B respectively which provide Wi-Fi cells for first and second user groups 600A and 600B respectively. Also connected to the network 600 are first and second Wi-Fi nodes 610A and 610B, the latter of which being coupled to network 600 via router 605. Second Wi-Fi node 610B is associated with Enterprise 660, e.g. Toronto Waterfront Marathon™, within which other first and second user groups 600A and 600B exist. Second user group 600B may also be connected to the network 600 via wired interfaces including, but not limited to, DSL, Dial-Up, DOCSIS, Ethernet, G.hn, ISDN, MoCA, PON, and Power line communication (PLC) which may or may not be routed through a router such as router 605.

Within the cell associated with first AP 610A the first group of users 600A may employ a variety of PEDs including for example, laptop computer 655, portable gaming console 635, tablet computer 640, smartphone 650, cellular telephone 645 as well as portable multimedia player 630. Within the cell associated with second AP 610B are the second group of users 600B which may employ a variety of FEDs including for example gaming console 625, personal computer 615 and wireless/Internet enabled television 620 as well as cable modem 605. First and second cellular APs 695A and 695B respectively provide, for example, cellular GSM (Global System for Mobile Communications) telephony services as well as 3G and 4G evolved services with enhanced data transport support.

Alternatively the first and second user groups 600A and 600B may be geographically disparate and access the network 600 through multiple APs, not shown for clarity, distributed geographically by the network operator or operators. First cellular AP 695A as show provides coverage to first user group 600A and environment 670, which comprises second user group 600B as well as first user group 600A. Accordingly, the first and second user groups 600A and 600B may according to their particular communications interfaces communicate to the network 600 through one or more wireless communications standards such as, for example, IEEE 802.11, IEEE 802.15, IEEE 802.16, IEEE 802.20, UMTS, GSM 850, GSM 900, GSM 1800, GSM 1900, GPRS, ITU-R 5.138, ITU-R 5.150, ITU-R 5.280, and IMT-1000. It would be evident to one skilled in the art that many portable and fixed electronic devices may support multiple wireless protocols simultaneously, such that for example a user may employ GSM services such as telephony and SMS and Wi-Fi/WiMAX data transmission, VOIP and Internet access. Accordingly portable electronic devices within first user group 600A may form associations either through standards such as IEEE 802.15 and Bluetooth as well in an ad-hoc manner.

Also connected to the network 600 are Social Networks (SOCNETS) 665, first and second personnel providers 670A and 670B respectively, e.g. Manpower™ and Adecco™, catering service provider 670C, e.g. Daniel & Daniel (Toronto, Canada), and first to second partner enterprises 675A and 675B respectively, e.g. Scotiabank™ and Running Room™, as well as first and second servers 690A and 690B which together with others, not shown for clarity.

First and second primary content servers 690A and 690B may also host for example other Internet services such as a search engine, financial services, third party applications and other Internet based services.

Accordingly, an enterprise user or individual user (ENUINU) may exploit a PED and/or FED within an Enterprise 660, for example, and access one of the first or second primary content servers 690A and 690B respectively to perform an operation such as accessing/downloading an application which provides FCA-FCAP features according to embodiments of the invention; execute an application already installed providing FCA-FCAP features; execute a web based application providing FCA-FCAP features; or exploit FCA-FCAP features within another application. Similarly, an ENUINU may undertake such actions or others exploiting embodiments of the invention exploiting a PED or FED within first and second user groups 600A and 600B respectively via one of first and second cellular APs 695A and 695B respectively and first Wi-Fi nodes 610A.

Within system 700 protocol stack 724 is shown as IEEE 802.11 protocol stack but alternatively may exploit other protocol stacks such as an Internet Engineering Task Force (IETF) multimedia protocol stack for example. Likewise AP stack 725 exploits a protocol stack but is not expanded for clarity. Elements of protocol stack 724 and AP stack 725 may be implemented in any combination of software, firmware and/or hardware.

In accordance with an embodiment of the invention a method and/or system is provided allowing a user to quickly and easily request and receive data relating to the whereabouts of other users. The system sends a request for location of a user from a PED and/or FED to a user notification server containing the requesting user information and receiving user information. The user notification server receives the request, retrieves the device type using the receiving user information and chooses the appropriate push notification service to use based on the device type. The user notification server then sends the request for location to the selected push notification service. This request for location information is then received by the receiving user's PED and/or FED application, which displays the request along with the requesting user information and a corresponding action. Upon execution of the action, the user's device retrieves location data, and sends a response intended for the requesting user containing the location data and receiving user information to the user notification server. The user notification server then receives the response and retrieves the device type of the requesting user and chooses the appropriate push notification service to user. The user notification server then sends the response to the selected push notification service wherein it then received by the requesting user through the appropriate PED and/or FED application. The response is then received by the appropriate PED and/or FED application which then displays to the requesting user the receiving user's location data.

According to an embodiment of the invention the receiving user's location data is displayed on a map to the requesting user. Within another embodiment of the invention the receiving user's location is presented on a map in association with a location of an event involving the receiving user allowing the receiving user to make a judgment with respect to the receiving user's time of arrival at the event. Within another embodiment of the invention the receiving user's location is presented on a map in association with a location associated with the requesting user allowing the requesting user to send a modified event request to the receiving user that allows the event to occur earlier and/or closer to the originally intended start time.

Within another embodiment of the invention the map displayed to the requesting user is parsed from a map provider/map service including information from one or more third party service providers (which may be the same enterprise as the map provider/map service.) In this instance the requesting user is presented with additional information such as local traffic, for example, allowing the requesting user to make a more accurate judgment. Within another embodiment of the invention the receiving user may be presented with a map wherein the receiving user location data has been parsed by a map provider/map service together with the location of an event associated with the receiving user and third party information such that the user is presented with distance/time information based upon archived data and/or real time conditions. Accordingly, the receiving user may be provided with additional data by the requesting user such as an alternate route or alternate destination. For example, rather than having a volunteer arrive late at a destination where their help may be not needed by the time they arrive, e.g. all the runners have left, then they may be directed to a new destination, e.g. finish line, hydration station, changeover point, etc. so that they are able to contribute to the event. In other embodiments of the invention the alternate destination is determined by the application in dependence upon current user location and the location(s) established within the application for the event to which the user is currently associated with.

Within the embodiments of the invention described supra the requesting user request is described as being communicated via a push notification server. Within embodiments of the invention the push notification server is selected based upon knowledge of the user's device alone or it is selected in dependence upon the user's device in combination with the communication service determined in dependence upon the receiving user's address associated by the requesting user with the request. Accordingly, a phone number may cause use of a SMS service, an email use of an email application, a twitter handle use of Twitter™, a Facebook™ user name a post to the receiving user's Facebook™ wall, etc. In some embodiments of the invention an application that is discrete from other receiving user software applications may be employed whilst in other embodiments of the invention the application may be triggered from within another software application based upon the receiving user performing the action. In some instances the push notification server and the notification service features may require that the message include a URL which when accessed runs code on the receiving user's PED and/or FED to retrieve the location information and send this back for transmission to the requesting user.

Within other embodiments of the invention the receiving user may be able to add additional information rather than simply providing their location. Said information may, for example, be a limited text response, e.g. 140 characters, such that the additional information may be posted to a social media website/application within a profile associated with the event to which the receiving user is invited and their whereabouts sought. Within another embodiment of the invention the action performed by the receiving user triggers downloading of an application to their PED and/or FED wherein the application extracts the location data and transmits this.

In another implementation the sending of a request for location of a user is initiated from a list of users established in association with an event. This list may be generated by an organizer of the event or it may be created by user's registering for an event, e.g. volunteers to an event, users accepting a meeting request, etc. Within other embodiments of the invention such a list or lists may be part of an application for creating and running an event. Optionally, the list may be the contacts of a user on their PED and/or FED or within an application, e.g. email. In other embodiments of the invention the list may be associated with a directory, e.g. an enterprise staff directory. Within another embodiment of the invention the user address may be established through the selection of a member of a SOCNET and/or SOME wherein their information is provided confidentially to the requesting user rather than to all friends/contacts of the receiving user and/or requesting user. In another embodiment of the invention the receiving and requesting users may, for example, be members of a community, e.g. a dating service.

Within other embodiments of the invention the action of the receiving user may be audibly activated allowing them to perform the action or deny the action through an audio command, e.g. saying YES or NO, etc. In this manner a hands free operation for providing a response may be provided to users who are currently driving, engaged in an activity, etc.

Whilst embodiments of the invention have been described with respect to the organization of an event it would be evident to one skilled in the art that the embodiments of the invention may also be employed within other settings such as, for example, a mother seeking to find the current location of their daughter, son, husband, father, etc. without monitoring them continuously.

Accordingly, embodiments allow a user to ask, for example with a single button press/user selection, for the location of other users. In response to the request, the user can, for example with a single button press/user selection, choose to respond to the user. The requesting user then sees the location of the other user.

Within another embodiment of the invention the PEDs and/or FEDs of a group of users, e.g. the organizer(s) and invitee(s) of an event, may have an application in execution wherein each of the user's devices knows the IP address of all or a subset of the devices associated with the other users. Accordingly, the communications may be performed peer-to-peer with no server in the middle for data direction. Within such an embodiment each device should acquire the other IP addresses, which may for example be through an initial service running on a server that they connect with when the event is being established and they are being invited. In the context of an event, when the devices running an application according to an embodiment of the invention then they may initially connect to acquire event information then they would also receive the IP addresses of all the other devices currently associated with the event which would be connected to the user list. Subsequently, upon another connection of the user's device to the event server then the IP address list updated or alternatively a list of IP addresses may be sent to their IP address with event association information allowing the application to add these IP addresses in respect of the event Then when a “Where are you?” request is sent to a user then it may be sent directly from the requester device to the IP address of the receiving user's device, and the application would handle the display and response actions on both sides. Accordingly, a temporary closed messaging system between devices based on their IP addresses would be established where the temporary closed messaging system is associated with an event and location information is only provided in response to a specific request that the recipient approves in a discrete process. In the case(s) where IP addresses are changing then a server may be employed as a relay point, with the devices keeping it updated with their IP addresses. Embodiments of the invention of such a configuration would bypass the requirement for a specific push notification service to be available for each device type. As such the embodiments of the invention in this manner would means the application provides its own “push notification service” which would be independent of any device type(s).
